IMPROVEMENT IN MACHINES FOR MAKING CIGARS.

Specification forming part of Letters Patent No.' 32,993, dated August 6, 186i.

by declare that the following is `a full, clear,

and exact description of the same, reference being had to 'the accompanying drawings, making a part of this Specification, in Which- Figure l is a side elevation of the machine; Fig. 2, a plan or top View; Fig. 3, a longi tudinal vertical section inside the frame; Fig. Ll, an end elevation.

The other' iigures will be explained in their natural order.

Like letters of reference indicate the same parts in each of the several gures.

X is the frame supporting the rest lof the machine.

l A'is the main driving-pulley through which- 'motion' is communicated to the machine. On

On the end of each of these rolls is a pinion,-

c c', gearing into the gears D D. p

H is a lever or handle attached to the segment F', by means of which the segments are rotated about their centers, and thereby the rolls G G elevated or depressed.

I I are twobottom rol-ls, also supported from the centers d d', and movable with the rolls G- G'.

K is an endless7 belt or apron running over the cylinders E E and between the rolls G I and G I', and forming between the two sets of rolls a loop, e, for the reception of theunrolled filling for a cigar.' This is' more fully seen in Fig. 5, in which the dotted lines show the position of the' rolls when elevated by means of the handle H andV segments F F.

The pinions on the rolls G G cause them to feed the belt through gradually, and thus giving arolling gmotioll` to anything confined in the loop c of belt. The belt also serves as an apron'on which to feed in the wrappers or covers to the cigars.

Lis va brush for brushing the end of the wrapper down l into the loop, and thereby starting it to roll round the filling..

M is another brush i'or applying paste to the last end of the wrapper as it comes round, and

. thus enable it to be stuck down and to form Aa smooth end.

N is a rotary cutter for cutting oif the end of the cigar after the wrapper is wound round.

This cutter is on the end of a shaft supported y in a box, f, which ismovable up and down by v the handle or lever y. Motion is communicated t0 thel cutter from the pulley It on the main shaft by a belt, fi.

k is a cutter composed of a series of circular saws, for shaping the small end of the filling before the wrapper is rolled on. The sizes of the saws are so graduated as to give to the end of the cigar thesuitable form. These cutters are seen more clearly-in Fig.` 6.

O is a rotary header, consisting of a rod of iron or other metal, supported in a bearing, Z, with a pulley, m, on one end, and in the other end a conical h ole, a, of a forni corresponding to the form ofthe small end of the cigar when finished.` 'In the rod O, between the two supports of the bearing l, is a groove, into which a crotched lever, is inserted, for the purpose of moving the header up to o'rback from the cigar by sliding it in the bearing Z. Fig. 7 shows two views of the header, the upper one being a side view in partial section, and the lower a plan of the end of rod having the conical cavity, and showing a slot, o, connecting with said cav-ity to admit the wrapper.

p is a small crank` made inthe rod O, and attached by the connection 'q 'tothe spring 1,

by means of which the slot o is' always're` turned to the top when the header `is not in l use. The header is put in` motion by means ofA the belt S from the pulleyt on the main shaft.` The belt is slack,except when tightened by the binder u; therefore the crank and spring are sufficient to keep the header in place 'and cause the belt-to slip, except when the binder is applied.

Having thus fully described the construction of the several parts, I will proceed to dei Scribe their operation in the manufacture ofa `wound around the filling. .Now bring up the .which gives to the header O4 a rotary motion l and iinishes the end of the cigar; and, lastly,

vout off the other end by means of cutter N.

some one of the common right-andrleft movef.

cigar. Supposing the rolls G G and "i l' to be elevated, as shown by the dotted lines in Fig. 5, the rolls, bythe operationof elevating, are sufficiently thrown apart to give free access to the loop e ofthe belt, which is' kept Aof a suitable size to receive. a sufcient quantity of filling by making the pinions c con the rolls G G" smaller than the rollers, therebyl feeding inan eXtra quantity of the belt'whe'n they are rotated around the large gears. by the process of elevating. Now, having. put into the loop a quantity of filling, throw down `the rolls, thereby forming a loop entirely enveloping the lling,vvth the exception lof a space between the rolls I l large enough tof-admit the Wrap: per. As soon asthe rolls are depressed the. filling bl eins to be rolled by the continuous motion of the belt'. Now bring up the out ter R and form the lling suitable for putting on the Wrapper,y after which lay a wrapper on the apron inthe position shoivu'in Fig. 2 at fv, the end of which is received by the roll G', bymeans of 'which and .the brush L it'fis header to the edge of the belt, readyto receive the projecting end of the Wrapper, which, as it comes under the brush M, receives Ythe paste and is received by the slot .o into the conical cavity. Now apply the binder u tothe belt s,

NOW throw up theA rolls, remove the nished cigar, and proceed as before. y

' A Wrapper toa cigar is one-half 'of' a leaf, and in order `to use bothfhalves the machine must be capable of runningin both directions,

which is easily accomplished by employing ments in transmitting power-to the machine through the main pulley, the only difference in the construction of the machine forl'that' purpose being the 'introduction' of another paste-brush on the other side of thefeed-roll's.

Fig. 8 shows a form for belt and rolls forgiv- 'ing the cigar'the peculiar vform common' to N ow,havin g fully V.described the construction .andoperation of my inachine, what I claim as ,and desire to 'secure by Letters my invention Patent, iisl. Running a belt in theform of'a loop, whereby 'a single' belt incloses and forms a bearing for the whole outside surface of the .ciganwith the exception lof a sufficient space Ato ladmit the.wrapper, the whole being constructed and operated in the manner and for vthe purpose set forth.

2. The use of a belt of unequal thickness for. the purpose of giving tothe cigar any're quired degree 'of taper, or for giving it any other deslrable form, the outline ofthe crosssectionof the belt corresponding with the outline of the longitudinal section of the cigar.

3. The use of the rotary brush L for facilitating the insertion 'of the Wrapperand to insure the Winding ofthe same around thelling.

4. The -use of a series of rotary cuttersvith eithersmooth or toothed edges, for ou-ttingand shaping the ends of cigars, when constructed and operated inthe manner and for the purpose set forth.
